I noticed a huge grey area over the past couple of days and have made a ticket with respect to it. I figured some people on here might already know the answer however:
When I select Race Change on the WoW shop and select a realm/character (in this case my Mage), hovering over it reveals the following message:
"Race changing to an Allied Race makes the character ineligible for their heritage armour set."
This looks like a huge grey area to me. Does it mean:
1) The race changed character simply can't use the Heritage armour, even if you unlock it legitimately by levelling an allied race from 20 - 110?
2) The race changed character is ineligible to unlock their heritage armour set?
3) Only allied race characters that have been levelled from 20 - 110 can use heritage armour?
If it means either of the former two then I would probably stop levelling my Nightborne Monk immediately as I am wanting to have the heritage armour on a Nightborne Mage (which I will change my Blood Elf Mage into).
